2 Claims. (Cl. 24116) This invention relates to chain slides and more particularly to a lariat chain slide which is adapted to vary the size of a loop of flexible material which extends about the neck of a person as an article of jewelry.

One of the objects of this invention is to provide a slide.

which may be moved to vary the size of the loop of a flexible cord or chain about the neck of the wearer and still permit the easy insertion or removal of the chain or flexible cord from the slide.

Another object of this invention is to provide an arrangement whereby the two lengths of flexible material may be securely held in the position to which a loop of flexible material is adjusted.

And still another object of the present invention is to provide a slide comprising a minimum number of inexpensive parts, easily assembled for economy of manufacture while retaining the positive gripping action and lightness of weight necessary in an article of jewelry.

Chain slides used as jewelry have had a bulky appearance in the past. This condition is abhorrent to the esthetic sense associated with jewelry. This undesirable condition is overcome in the present invention by employing a new clasping structure.

Like reference numerals refer to like parts in the accompanying drawings, wherein:

Figure 1 is a perspective view of the new and improved chain slide.

Figure 2 is a perspective view of a modified form of chain slide shown in Figure 1.

Figure 3 is a plan view of the chain slide depicted in Figure 1 showing a piece of jewelry chain gripped in selected position.

Figure 4 is a side elevational view of the form shown in Figure 1.

Figure 5 is a sectional view taken along line 5-5 of Figure 4 looking in the direction of the arrows.

Figure 6 is a longitudinal sectional view showing the clamping medium in open position as contrasted to the closed position shown in Figures 1, 3 and 4.

Referring to the drawing wherein reference character 10 generally designates the new and improved chain slide; a body member 11 is provided having upturned lateral sides saw toothed as at 12 and 13. One end is curled into a tubular portion 14 having an orifice 15. The opposite end 19 is turned up and provided with a U-shaped slot 16 to form a bifurcated stop.

A conventional coil spring 17 is provided, with one end positioned in orifice where it is anchored by the tubular portion 14. A hollow knob 18 having an orifice 20 which receives the opposite end of coil spring 17 is anchored 2,830,347 Patented Apr. 15, 1958 thereto by compressing knob 18 at orifice 20. U-shaped slot 16 receives the coil spring 17 with the knob 18 abutting the end 19 under the tension of coil spring 17.

In operation, face 21 of chain slide 10 may be provided with an artistic design. A chain having opposite ends 23, 24 is placed over saw teeth 12 and 13. Coil spring 17 is then placed over the chain with spring 17 in the U slot 16 and knob 18 abutting bifurcated to retain the spring adjacent the upper surface of the base end 19 as shown in Figure 4.

The modified form shown in Figure 2 varies from the form shown in all the other figures in that coil spring 17 is passed through and secured in tubular portion 14A. Orifice 15 is dispensed with. One end of the body member 11 is turned up in the form of an ear 19A. A knob 18A is anchored to both ends of spring 17 in the same manner as previously described.

Having illustrated and described preferred embodiments of the present invention, by way of example, but realizing that structural changes could be made and other examples given without departing from either the spirit or scope of this invention, I claim:

1. A chain slide for use as an article of jewelry comprising a body member having a base and upturned saw toothed lateral sides with one end of the base comprising a tubular portion having an anchoring orifice, the other end being formed from the base at an obtuse angle into a bifurcated stop having a slot, a coil spring having one end secured in said anchoring orifice, a knob larger than the bifurcated stop and provided with a spring receiving orifice, to secure said knob to said spring through said orifice, whereby said spring may assume a position adjacent said base between said upturned saw toothed lateral sides, the diameter of said spring being smaller than the bifurcated stop slot so as to lay therein and yieldingly hold said knob against said bifurcated stop.

2. A chain slide for use as an article of jewelry comprising a body member having a base and upturned saw toothed lateral sides with one end of said base comprising a tubular portion and the other end of said base being formed into a bifurcated stop having an open ended slot, said bifurcated stop being positioned at an obtuse angle to said base, a knob larger than said slot, an elongated spring of a diameter to fit in said slot, means adapted to fasten one end of said spring to said tubular portion and means to fasten the other end of said spring to said knob, said spring in stretched position having one end insaid slot yieldingly forcing said knob against said bifurcated stop with the stretched spring lying prone adjacent said base between said upturned saw toothed lateral sides.
